Method for the conversion of monophase uranium-plutonium monocarbide in (UPu)O2 contained in irradiated nuclear fuel

Creators

Description

The method of conversion of (UPu)C in irradiated (UPu)O2 is characterized in that one heats the fuel in CO2 to a temperature between 10000C and 11000C and hence obtains an oxidation product soluble in nitric acid. (UWI)
